Valve replacement in africa

Trust Saidi, Tania S Douglas
The treatment of rheumatic heart disease presents a medical and surgical challenge, particularly in developing countries, where the disease is prevalent. Most of these countries find it prohibitively expensive to import heart valve prostheses that are required for treatment and are largely manufactured in the United States and Europe. Even if the valves were available, the absence of facilities to conduct open-heart surgery for valve replacement results in many people from developing countries dying needlessly of the disease...

Tropical endomyocardial fibrosis (EMF) is a neglected disease of poverty that afflicts rural populations in tropical low-income countries, with some certain high-prevalence areas. Tropical EMF is characterized by the deposition of fibrous tissue in the endomyocardium, leading to restrictive physiology. Since the first descriptions in Uganda in 1948, high-frequency areas for EMF have included Africa, Asia, and South America. Although there is no clear consensus on a unified hypothesis, it seems likely that dietary, environmental, and infectious factors may combine in a susceptible individual to give rise to an inflammatory process leading to endomyocardial damage and scar formation...

BACKGROUND: There are few African data available on rheumatic heart disease (RHD). AIM: To provide data on the clinical characteristics and treatment of patients with RHD hospitalized in sub-Saharan Africa. METHODS: The VALVAFRIC study is a multicentre hospital-based retrospective registry of patients with RHD hospitalized in African cardiology departments from 2004 to 2008. RESULTS: Among 3441 patients with at least one mild RHD lesion seen on echocardiography in 5 years in 12 cardiology departments from seven countries, 1385 had severe lesions (502 men; 803 women; mean age 29...

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) has become the standard of care for inoperable patients with severe aortic stenosis and is an alternative to conventional surgery for high-risk aortic valve replacement (AVR) patients. There is a positive correlation between severity of pre-operative patients and hospital costs. The aim of this study was to compare empirically derived costs of the two therapies in South Africa. METHODS: The cost-comparison analysis was performed with a MediClinic database including 239 conventional isolated AVR (cAVR) and 75 TAVI cases...

BACKGROUND: Children and adolescents with end-stage renal disease (ESRD) in sub-Saharan Africa may have the worst outcomes globally. Barriers to management include late presentation, poor socioeconomic conditions, absence of medical insurance, limited diagnostic facilities and non-availability of chronic renal replacement therapy (RRT). Our study was to determine the incidence, aetiology, management and outcomes of paediatric ESRD in a tertiary hospital in Nigeria. METHODS: A retrospective case review of paediatric ESRD at the University College Hospital Ibadan, Nigeria, over 8 years, from January 2005 to December 2012...

This article outlines the arguments against cusp extension, which were put forward at the debate entitled "Repair options in rheumatic aortic disease in young patients" at the Symposium on Surgery for Rheumatic Heart Disease organized by The World Society for Pediatric and Congenital Heart Surgery at The Sixth World Congress of Paediatric Cardiology and Cardiac Surgery, February 17-22, 2013, Cape Town, South Africa. We propose that cusp extension should be avoided because (1) these patients are usually old enough to receive the same valve substitutes as adults, (2) lack of antibioprophylaxis compliance will likely result in early reintervention, (3) cusp extension mandates rerepair within four to five years and is more expensive in the long term, and (4) it is fraught with myocardial ischemic complications...

BACKGROUND: Cardiac disease in pregnancy is a common problem in under-resourced countries and a significant cause of maternal morbidity and mortality. A large proportion of patients with cardiac disease have prosthetic mechanical heart valve replacements, warranting prophylactic anticoagulation. AIM: To evaluate obstetric outcomes in women with prosthetic heart valves in an under-resourced country. METHODS: A retrospective chart review was performed of 61 pregnant patients with prosthetic valve prostheses referred to our tertiary hospital over a five-year period...

BACKGROUND: The West African sub-region has poor health infrastructure. Mechanical valve replacement in children from such regions raises important postoperative concerns; among these, valve-related morbidity and complications of lifelong anticoagulation are foremost. Little is known about the long-term outcome of mechanical valve replacement in West Africa. We sought to determine the outcome of mechanical valve replacement of the left heart in children from this sub-region. METHOD: We conducted a retrospective review of all consecutive left heart valve replacements in children (< 18 years old) from January 1993 - December 2008...

The incidence of CKD (Chronic kidney disease) in Nigeria has been shown by various studies to range between 1.6 and 12.4%. We have shown that the burden of renal disease in Nigeria is probably significantly higher than any previous study on end-stage renal disease (ESRD) has documented, as most studies are hospital-based and fail to include the many patients who do not have access to hospital care. The increased prevalence of ESRD among blacks in the United States and South Africa compared with other races also suggests that ESRD may be more prevalent in Africa than in the United States and other developed nations...

The history of using homologous cardiac valves dates back more than 30 years. Through the years emphasis was placed on the optimization of graft retrieval, preservation techniques and clinical application. A cardiac homograft valve bank was established at the Department of Cardiothoracic Surgery, University of the Free State, Bloemfontein in 1982. A retrospective analysis was performed on all allograft data since 1984. Since the first valve was successfully procured and transplanted in 1984, 2,540 aortic and pulmonary homografts were harvested from 1,792 donors, of which 1,545 [989 (64%) aortic and 556 (36%) pulmonary] were released for clinical use...

Right-sided forms account for one-fourth of endomyocardial fibrosis cases in central Africa. A 50-year-old female patient with endo- myocardial fibrosis presented with unusual calcifications of the right ventricular endocardium that embedded the tricuspid valve papillary muscles. Bioprosthetic tricuspid valve replacement together with right ventricular endocardectomy was performed with a good clinical outcome.

This study was a retrospective review of patient charts of a relatively large number of patients with cardiac disease in pregnancy in a developing country. Ninety-five patients were evaluated; the majority (n = 36) were in the age group 21-25 years. Rheumatic heart disease was the commonest aetiology; eight women required balloon mitral valvuloplasty and one had a valve replacement at 32 weeks' gestation. There were no maternal deaths but morbidity was high; 13 patients were admitted in cardiac failure, nine had atrial fibrillation and three required intensive-care management...

BACKGROUND AND OBJECTIVES: Long-term anticoagulation therapy is essential to prevent thrombo-embolic events in patients with mechanical valve replacements. In order to offer indigent patients mechanical heart valve replacement surgery, dedicated anticoagulation clinics are necessary for follow-up. This study assessed the safety and efficacy of lifelong oral anticoagulation therapy in Johannesburg General Hospital mechanical heart valve replacement recipients. The incidence of bleeding and thrombo-embolic complications was documented in three groups of patients with mechanical valve replacements...

BACKGROUND: Cardiovascular disease is an important cause of morbidity and mortality in South Africa. The Southern Africa Stroke Prevention Initiative (SASPI) found a high prevalence of stroke in the rural Agincourt subdistrict, Limpopo province. Hypertension is the commonest vascular risk factor in our population and it is essential that primary care services be adequately equipped to detect and treat hypertension. The aim of this study was to assess the number, accuracy and working condition of blood pressure measuring devices (BMD) in the clinics that serve the field site, and to assess the clinic sisters' perceptions of the availability of antihypertensive medication and aspirin...
